Transmission of beams through arrays of coaxial apertures in a thick, perfectly conducting screen is investigated using an angular spectrum approach. It is shown that the transfer function of the screen is complex and strongly dependent on the wavelength and polarization of the incident field and the geometric properties of the screen. Examples of changes in the angular spectrum composition of linearly, radially and azimuthally polarized beams as well as near-field intensity patterns are presented and the role played by different resonant transmission mechanisms discussed.
